Alicia's Keys by Native Instruments is a Virtual Instrument Audio Plugin for Windows and Mac OS X. It includes, and is therefore "powered by", Kontakt Player, which functions as a VST Plugin, an Audio Units Plugin, an RTAS Plugin and an AAX Plugin.

Alicia's Keys is a software instrument that recreates Alicia Keys' personal grand piano with authenticity and playability. Developed in close collaboration with the Grammy-winning artist, the software is used as the primary instrument on her new album and on the current world tour. Alicia's Keys is a unique way for musicians of all experience levels to utilize Alicia's acclaimed signature piano sound in their own music production, live performance, and recreational playing.

Designed as a comprehensive digital recreation of Alicia Key's own custom Yamaha "C3 Neo" grand piano, and based on Native Instruments' Kontakt 4 sampler platform, Alicia's Keys provides a soulful and intimate piano sound that perfectly accommodates R&B, soul and pop styles. The instrument was meticulously recorded in Alicia's personal studio by her engineer Ann Mincieli and sampling expert Thomas Scarbee over the course of two years, using vintage microphones and high-end outboard studio gear that produced "an exquisite piano tone with supreme sonic fidelity".

Utilizing 17 GB of high-resolution samples with 12 discrete velocity layers per note, and sophisticated emulation of crucial sonic aspects like key release, sustain pedal functionality and sympathetic resonance, Alicia's Keys sets a benchmark in the digital recreation of acoustic instruments. The convenient user interface of the software gives intuitive control over the sound to further adjust it to the specific musical context and personal playing style, and also includes a studio-quality convolution reverb that provides various authentic room ambiences ranging from a small piano chamber to a large stage or concert hall.

Alicia's Keys can be used on any Windows and Macintosh computer with the included free Kontakt Player, and can also be loaded into the full-featured Kontakt 4 sampler for additional in-depth sound editing.
